The New England National Scenic Trail (NET) is a 215-mile hiking trail route that has been in existence for over half a century. The NET travels through 41 communities in Connecticut and Massachusetts, and is comprised primarily of the historic Mattabesett, Metacomet, and Monadnock (M-M-M) Trail systems.

The NET travels through classic New England landscape features: long-distance vistas with rural towns as a backdrop, agrarian lands, un-fragmented forests, and large river valleys. The trail also travels through colonial historical landmarks and highlights a range of diverse ecosystems and natural resources: mountain ridges and summits, forested glades, wetlands and vernal pools, lakes, streams and waterfalls.

Since the federal designation in 2009, there have been some noteworthy changes to the historic route, including a 4-mile extension to Long Island Sound in Connecticut and a 22+ mile eastward deviation from the historic Metacomet-Monadnock Trail in Massachusetts.
